  • Publication number: 20220123643
    Abstract: The actuator includes a magnetic drive mechanism to relatively move the movable body with respect to the support body. The magnetic drive mechanism has a magnet and a coil. The connecting element connected to the support body and the movable body is a viscoelastic member. The viscoelastic member has a temperature characteristic that a loss tangent (Tan ?) thereof measured by a dynamic viscoelasticity measurement decreases as a temperature rises. When using a silicone gel as the connecting element, the decrease in the peak value of the acceleration of the movable body caused by the decrease in the current flowing through the coil is cancelled by the increase in the peak value of the acceleration of the movable body caused by the decrease in Tan ? of the silicone gel. Therefore, the oscillation of the movable body is unchanged even if a temperature changes.
